摘要: Publisher Summary This chapter reviews formulations and some procedures that have been suggested for the solution of Steiner Problem in graphs. It presents definition results associated with classical also known as Euclidean (ESP). The discusses graphs where an undirected graph (SPUG) a directed (SPDG) are defined. transformation SPUG SPDG. provides overview on Lawler algorithm SPUG. chaptre four integer programming graphs, compares linear relaxations three these formulations, describes application Benders method to solve one illustrated by example. methods based computational results.
